Plastic Elastomer Seated Butterfly Valves
Type 57, PD Series/Lug Body

Chemline elastomer seated butterfly valves up to 24" have been improved. The new Type 57 replaces Type 56 up to 14". Type 57 body, disc and seat have been redesigned to offer better flow characteristics and lower torques. Stem torques are unaffected by excessive flange bolt torques. New frp gear operators are available. Valves up to 16" have top flange with standard ISO 5211 mounting platform and shaft dimensions for easy actuation. A large selection of body, disc and seat materials permit these valves into a wide range of on/off and throttling control applications.
